Abstract:

Organized cybercrime occurs in different forms and has become more frequent and
consequential. How do we quickly, accurately, and comprehensively identify these
threats? How can we reduce the attack surface and improve defensive agility? The
necessary steps to make meaningful progress and answer these questions require
integrating 1) a variety of scientifically rigorous empirical methods including user studies,
machine learning, and code analysis to translate an abstract concept into quantifiable
information, and 2) data-driven approaches to enhance the agility of defenders to respond
to these attacks.


In this talk, I will highlight the contribution of empirical methods to systems security with
three examples from my work. I present systems to uncover and explore three large-scale
adversarial activities including ransomware, online scams, and in-browser covert
crypto-mining. I illustrate how data-driven approaches offer empirical techniques to study
contemporary security incidents by exposing underlying aspects of these threats, leading
to more effective defensive techniques and security models that are more closely aligned
with today’s cybersecurity landscape.
